SCAN921025SLC

Overview

The SCAN921025SLC is a serializing interface component manufactured by National Semiconductor, designed for high-speed data transmission in demanding environments. It features ten LVCMOS or LVTTL inputs and a single LVDS output, operating at data rates up to 800Mbps. The device functions within a supply voltage range of 3V to 3.6V and supports an extended operating temperature range from -40°C to 125°C. Packaged in a 49-lead NFBGA (7x7mm) surface-mount format, it facilitates point-to-point differential interconnects via backplane or cable connections.

Feature Summary

• Supports serialization of ten parallel digital data channels into a single high-speed differential output stream
• Capable of operation in extreme thermal conditions up to 125°C ambient temperature
• Utilizes Low Voltage Differential Signaling (LVDS) technology for robust noise immunity
• Accepts standard logic-level input signals including LVCMOS and LVTTL

Applications

• Automotive electronic systems requiring high-temperature reliability
• Industrial factory automation control interfaces
• High-speed data acquisition systems utilizing backplane or cable interconnects

Procurement Notes

Verify component authenticity carefully as the part is obsolete. Confirm RoHS compliance status, which is listed as non-compliant. Check for lead-free alternatives if environmental regulations require it. Validate package integrity upon receipt due to potential long-term storage effects on solderability.

Selection Notes

Select this component when ten-channel parallel-to-serial conversion is required with LVDS output. Ensure the system design accommodates the specific 3V to 3.6V power supply constraints. Verify that the PCB layout supports the 49-NFBGA footprint and thermal requirements for operation up to 125°C.

Part Context

This serializing chip belongs to a specialized LVDS interface family introduced by National Semiconductor around 2005. It was engineered specifically for harsh environment applications where standard commercial components fail. The device complements the SCAN921226H deserializer to form a complete high-speed serial link solution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, engineers must evaluate pin-compatible alternatives or redesign the interface using modern serializers that meet current RoHS standards.
